61) Tray sorter
A high speed type of sorting conveyor with sorts in the 250 cases per minute range, this type consists of a continuously moving train of independent trays that move in a straight line and recirculate in either a horizontal or vertical (over and under) closed loop. At the proper moment, controls cause the tray to tilt to either side, thereby discharging the load to the desired take away lane.
62) Order picking
Order picking or order selection is the process of retrieving individual items (from storage locations) for the purpose of fulfilling an order for a customer. Schemes by which to achieve efficient order picking will vary widely. However, in all cases it involves locating the items in storage; creating a plan for retrieving the items; physically picking the items (either automatically or manually); sorting and/or assembling them into discrete orders; and in the end even packaging the orders for delivery. Although defined as a process, order picking cannot be achieved without the appropriate computer software and mechanical equipment, including the storage medium, such as pallet racks, shelving, AS/RS (including carousels) and flow delivery racks, and a means for transporting items from receiving to storage and from storage to packaging and shipment. A variety of industrial trucks and conveyors will be found in most order picking applications. Order picking may also involve robotic like devices for physically picking discrete items from their storage location. See also Warehouse Management Systems or WMS .
